To all whom it may concern.-

Be it known that I, EDMUND H. LUNKnN. a citizen of the United States,residing at Oincinnati, Ohio, have invented certain new and usefulImprovements in Sectional Windows, of which the following is aspecification.

My invention relates to window constructions, and is designed to providean economical and effective structure whereby windows may be furnishedof any desired size.

The underlying principle of my invention consists in building up awindow of units, so that by adding these units either laterally orvertically a window of any desired form or size may be provided.

The invention concerns more particularly a window having a swingingglass -carrying frame arranged in a main frame, though it will beunderstood that I do not wish to limit myself in this respect.

In the present embodiment of my invention the window is built up ofunits, each of which is composed of a main-frame section havingpivotally arranged within it a swinging frame carrying the glass, and bythis arrangement a window is provided which may be adjusted to securevarious ventilating effects, because of the fact that each of the units,which are disposed at different points about the windowopening, isprovided with a swinging sash, and by opening this or closing it andopening others different effects may be secured in the ventilation ofthe building.

The invention consists in the features and combination and arrangementof parts hereinafter described, and particularly pointed out in theclaims.

In the accompanying drawings, Figure 1 is an inside view of one unit orsection of the improved window-frame. Fig. 2 is a sectional view on liney 3 of Fig. 1. Fig. 3 is a Sectional view on line :20 w of Fig. 1. Fig.4 is a sectional view on line 4 4 of Fig. 1. Fig. 5 is a sectional viewon line 5 5 of Fig. 1. Fig. 6 is a sectional view on line 6 6 of Fig. 1.Fig. 7 is a central vertical sectional view of one of the unitscomposing a window, showing the swinging or inner frame partly open.Fig. 8 is a front view of the lock-post with a part in section. Fig. 9is a sectional view on line 9 9 of Fig. 8, showing also a part of theframe-section and of the swinging sash or supplemental frame. Fig. 10 isa sectional view on line 10 10 of Fig. 9. Fig. 11 is an inside face Viewof a window composed of four of the units bolted together. Fig. 12 is asectional view on line 12 12 of Fig. 11, showing the main-frame sectionsof the unit bolted together by means of wrought-iron strips. Fig. 13 isa perspective view of one of the main-frame sections, showing thearrangement of the flanges. Fig. 14 is a view similar to Fig. 12,omitting the wrought-iron strips.

As above stated, one object of the invention is to provide a unit whichwhen attached to other like units by adding the same thereto on top oron the bottom or at either side will permit a window to be built up ofvarious shapes and sizes. Each unit is composed of a main-frame section,preferably of cast metal, (indicated at A in Fig. 13.) This is ofsubstantially rectangular form and is provided with flanges 1 2, 3 4.The flanges 1 and 2 are continuous one with the other, and they extendalong two of the adjacent sides of the mainframe section. They lie inthe same vertical plane, whereas the flanges 3 and 4, which are alsocontinuous one with the other, lie in a different vertical plane fromthat of the flanges 1 and 2, though the said flanges 3 and4 extend alongthe remaining sides of the main-frame section. In other words, theflanges 1 2, 3 4 are so displaced in relation to each other that therear face of the flanges 3 4 is in approximately the same vertical planeas the front face of the flanges 1 2. Each pair of flanges as, forinstance, 1 2 at their point of juncture are beveled, forming aninclinedv corner, as at 25. The ends of these flanges are also beveled,forming double inclines 25 25. This beveled construction of the flangesis carried out in connection with the other flanges 3 4. The main-framesections of the units carry on their inner sides sockets, as at 6, andalso*stop-strips 7 and 8. The swinging section or sash of the unit isprovided with pintles, as at 5, Fig. 1, adapted to fit in the socket 6and permit the supplemental frame or sash to swing within the main-framesection of the unit, and this supplemental or swinging section isprovided with suitable stopstrips such, for instance, as shown at 11,Fig. 7- adapted to cooperate with the stop-strips on the main frame ofthe unit to make a weathertight joint. The glass is held within thesupplemental frame or swinging sash by means of putty 9, a flange 12,secured to the supplemental frame holding the putty in place and againstan integral flange 13, cast on the supplemental framey' Thesestop-strips and'the manner in which the supplemental frame is hungwithin the main-frame section are substantially the same in form andarrangement to those disclosed in Letters Patent of the United Statesgranted to BernardJ. H-ausfeld and Edmund H. Lunken, dated May 24,1904,Nos. 760,624, 760,625, and 760,626. r

In building up a window from units like the one described above theflanges 3 1 of one unit are arranged to flt against the face of theflanges l 20f ad jacent'units, and bolts passing through these flanges,as shown in Fig. 11, secure the units together. The construction andarrangement of the flanges are such that one unit may be placed on anyside of another unit, and when the units are all assembled, as shown inFig. 11, there will be no openings between the frame-sections of theunits, as the flanges will cover all the space between the saidmain-frame sections.

Fig. 14 illustrates the bolting together of the flanges, which arebrought directly in contact with each other, and Fig. 12 illustrates thebolting together of the flanges with wroughtiron strips 30, placedagainst the outer'faces of the flanges, the bolts being indicated at 29.These wrought-iron strips are particularly useful when the main sectionsare made in cast-iron or other metal which is liable to crack whensubjected to intense heat and suddenly chilled by water; but,'asaboveindicatcd, while preferably the metal frames are of cast metal theinvention can be carried out with frames constructed of other metal.

As shown in Figs. 4. and 7, the swinging frame is preferably provided atits lower edge with a lip or flange 14:, adapted to depend over thefront edge of the main frame, and thus protect the packing material inthe stop-strips from snow and rain, and at the top of the section orunit the main frame is provided with a depending lip 15, which extendsover the front edge of the swinging frame and keeps out the rain andsnow from the packing material at this point.

In order to lock the swinging frame when closed and also to tilt it toany desired position and hold the same inclined, a curved bar 17 ispivoted to the swinging frame at 22, the said bar passing through alock-post 16, screwed to the face of the main-frame section. The curvedbar is provided with notches 18 in its upper edge, which are adapted tobe engaged by a lock 19, pivoted to the post by a screw 20 and having atooth 21 adapted to engage the notch 18 in the locking-arm.

As shown in Fig. 7, when the swinging frame is tilted it may be held inthis position by the lock engaging with its tooth 21 into the notches ofthe rod or arm 17. As shown in Fig. 10, the locking-rod is pivoted tothe swinging frame at 22 so as to swing horizontally, and when thewindow is closed the locklng-rod may be swung aside, and it will thenact as a lever to draw the swinging frame into 'close contact with themain-frame section.

adapted to contact with the front face of the post, which thus acts afulcrum. In order to better provide this fulcrum, the screw 20 isutilized as a bearing for the side of the locking-bar, and this screwmay be adjusted out or in, so that different leverage effects may besecured. When the locking-bar is swung to the position shown at Fig. 10,it may be held by the catch 23, which is pressed upwardly by a spring2 1. By simply pressing this catch downwardly the locking-bar may bereleased, and then by bringing it axially into line with the opening inthe locking-post it is ready to pass through the said opening and permitthe supplemental frame or sash to be tilted.

The lock 19 may be swung up out of connection with the locking-bar in anobvious manner. The tooth 21 is made of fusible material soldered to thelock 19, so that in case a certain degree of heat is presentin thebuilding the fusible tooth will melt, and as the swinging supplementalframe is heaviest at the bottom the said frame will close automaticallyshould it be open at the time the fire or excessive heat occurs.

It will be noticed that the screw 20 serves for two purposes,acting as ahinge for the drop-lock 19 and also as a fulcrum for the locking-bar 17to work against when it is desired that this should act as a lever todraw the swinging frame close against the main frame.

The invention is not limited to the precise details disclosed herein, asthese may be varied' without departing from the fundamental principle.

The units are interchangeable, and the arrangement of flanges'betweenthem provides a continuous, flush, and unbroken surface.

I Each unit also is provided with an independent lock, and the differentswinging frames or sashes may be adjusted at pleasure to get differentventilating effects.
